    The present study reported a facile method for the determination of melamine in milk powder products based on the aggregation of reactant-free 5 nm gold nanoparticles (AuNPs). The strong electrostatic attraction between the positively charged exocyclic amine groups present in the melamine molecule and the negatively charged ions bound to the AuNPs induced aggregation of the AuNPs, resulting in visible color changes that could be seen with the naked eye and monitored by ultraviolet-visible (UV-Vis) absorbance spectra. The method shows high sensitivity with detection limits of 1 × 10-9 M for visual detection and 1 × 10-11 M for UV-Vis analysis, which is far below the safety limit of melamine ingestion in infant formula (1 ppm = 7.9 × 10-6 M) and the detection limit acquired by most AuNP-based melamine detection methods. Good recoveries were obtained over the range of 94.7-95.5% with a relative standard deviation of mean recovery (RSD) ranging from 1.40 to 5.81. The method provides a simple, feasible, fast and real-time detection of melamine adulterants in infant formula by the naked eye, without the aid of advanced instruments.

    This is a cross-sectional study on 218 pregnant mothers in an urban government Hospital.The study aimed to assess knowledge, attitudes and sources of information on breastfeeding. The results could be utilised to promote breastfeeding. Almost all the respondents (96.8%) intended to breastfeed their newborns. Most of them (74.8%) were knowledgeable about breastfeeding i.e. colostrum and breast milk was the best food, good for resistance against disease and allergy, filling up stomach easily, helpful in teeth development and maternal recovery after birth, increased bonding, was easy and economical. The two main misconceptions were mothers would stop breastfeeding when infant or mother was sick, and giving clear fluid to the exclusively breastfed infants to prevent dehydration. Most mothers (83.9%) responded positively towards breastfeeding i.e. it was easier than infant formula, had no negative effect on marital relationship or family care, would commence breastfeeding straight after delivery, agreeable to the banning of bottles and teats in hospital and they would not stop breastfeeding even if husband discouraged them. Only 56.9% of the mothers believed they could breastfeed their babies with modesty anywhere. The main sources of information were attained from the mass media (34.9%), antenatal class (32.1%) and other mothers with breastfeeding experiences.

    A diarrhoea outbreak had occurred among neonates delivered in a private hospital in Kedah from 15 August to 8 September 2002 involving 27 (55.1%) cases out of a total of 49 deliveries. Thirteen of them (48.1%) were admitted to either government or private hospitals for treatnzent while fourteen of them (51.9%) were managed at home. The main presenting feature was frequent yellowish to greenish watery stool not associated with vomitting. Investigations include active case finding, environmental inspection, sampling of stool specimens, identifying causative agents and identuying human carriers. All the diarrhoea eases (100%) were noted to have received infant formula feeding while in the private hospital. Staphylococcus aureus was isolated hom the milk scoop which was used for milk preparation. Nasal swabs of four (50%) nursing personnel were also positive for Staphylococcus aureus. One of them was positive for methycilline resistant Staphylococcus aureus (MRSA). The milk and water samples showed no signuicant bacterial contamination. Stool samples of these cases were negative for Rotavirus, Vibrio sp., Salmonella sp., Shigella sp. and Entamoeba coli. This outbreak of diarrhoea was noted to have a strong association with infant formula feeding in the hospital. Breastfeeding should be continuously promoted. Baby friendly hospital initiatives in private hospital settings need to be initiated.

    Cronobacter sakazakii is an emerging food borne pathogen which has been associated with outbreaks of a rare form of infant meningitis. Although the origin of the microorganism has not been established, several
    infection cases have been associated with the consumption of contaminated powdered infant formula (PIF). In the present study, growth characteristics of three C. sakazakii strains isolated from PIF samples and C.
    muytjensii strain ATCC 51329, which was formerly the ATCC Preceptrol™ strain for the quality control of
    ‘Enterobacter sakazakii’ prior to the taxonomic revision, were investigated in Tryptone Soya broth (TSB) and
    reconstituted PIF at 4, 10, 25, 37, 45 and 50ºC. The viability of heat treated cells of Cronobacter strains was
    evaluated by plating on Violet Red Bile Glucose agar (VRBGA) and the Druggan-Forsythe-Iversen (DFI)
    chromogenic agar followed by incubation at 37ºC. These strains were also subjected to higher temperatures
    between 52 to 60ºC to measure their thermal tolerance. The mean generation time of all Cronobacter strains
    were slightly lower in PIF than in TSB. C. muytjensii ATCC 51329 showed lower generation time in all culture
    media and all temperatures compared to the Cronobacter food isolates, but the results were not significantly
    different (P>0.05). The results also indicated that combination of PIF: DFI culture media had higher recovery at
    all temperatures compared to other combinations. Survival study also indicated that C. muytjensii ATCC 51329
    had higher D-value compared to food isolates at all incubation temperatures.

    Enterobacter sakazakii previously known as 'yellow-pigmented E. cloacae' has been classified as a new genus 'Cronobacter' based on taxonomic analysis and geno-and phenotypic evaluation. This pathogenic organism has been associated with rare form of infant meningitis and necrotizing enterocolitis (NEC) with high mortality rate (40-80%). Some cases have been linked to the consumption of contaminated powdered infant formula milk (PIF). The objective of this study was to determine the presence of Cronobacter spp. in PIF sold in Malaysia. A selective chromogenic agar, Brilliance Enterobacter sakazakii (DFI, Oxoid), was used for detection of Cronobacter strains. Presumptive Cronobacter isolates were identified using biochemical tests (API 20E and MicrogenTM) and molecular assays (SYBR Green Real-time PCR and 16S ribosomal DNA sequencing). All presumptive Cronobacter strains produced typical blue-green colonies and non-Cronobacter strains produced yellow colonies on Brilliance Enterobacter sakazakii agar (DFI formulation). A total of 12 presumptive isolates were selected from DFI agar and identified with biochemical and molecular tests. The results indicated prevalence of 12.5% C. sakazakii contamination from 72 PIF samples. Molecular detection methods such as Real-time PCR and 16S rDNA proved to have higher identification percentage compared to the biochemical tests. In this study, it was observed that molecular assays were suitable means for sensitive identification of Cronobacter strains in PIF samples.

    Pacifier nipples are in permanent contact with saliva and with the oral microflora therefore, act as a favoured site for the growth of biofilms. This research was conducted to identify the bacterial biofilms that has been found on the pacifiers that collected from local child nursery and to analyse the formation of biofilms by Cronobacter sp. during growth in infant formula milk. Pacifiers collected were analysed to obtain colony forming unit (CFU) and isolated bacteria were identified using several biochemical tests according to Bergey's Manual. Biofilm assay of three Cronobacter sp. were conducted using 24 wells microtiter plate and stained with 1% of crystal violet solution at different time interval: 6, 12, 18 and 24 h. The hydrophobicity of the bacterial cell suspension was evaluated using bacterial adhesion to hydrocarbons (BATH) method. Extracellular polymeric substances (EPS) analysis was done to identify percentage of carbohydrate and protein content by using phenol sulphuric acid method and Bradford method, respectively. The results obtained showed that the normal microflora bacteria were the most abundant microorganisms that were found on the pacifier with the main genus isolated was Staphylococcus sp., Enterobacteriaceae sp. and Clostridium sp. Based on biofilm and EPS analysis, Cronobacter sakazakii formed a strong biofilms after 18 h, with carbohydrate was identified as main component of EPS.

    The purpose of this study was to improve the survival of Bifidobacterium animalis subsp. lactis 10140 during freeze-drying process by microencapsulation, using a special pediatric prebiotics mixture (galactooligosaccharides and fructooligosaccharides). Probiotic microorganisms were encapsulated with a coat combination of prebiotics-calcium-alginate prior to freeze-drying. Both encapsulated and free cells were then freeze-dried in their optimized combinations of skim milk and prebiotics. Response surface methodology (RSM) was used to produce a coating combination as well as drying medium with the highest cell viability during freeze-drying. The optimum encapsulation composition was found to be 2.1 % Na-alginate, 2.9 % prebiotic, and 21.7 % glycerol. Maximum survival predicted by the model was 81.2 %. No significant (p > 0.05) difference between the predicted and experimental values verified the adequacy of final reduced models. The protection ability of encapsulation was then examined over 120 days of storage at 4 and 25 °C and exposure to a sequential model of infantile GIT conditions including both gastric conditions (pH 3.0 and 4.0, 90 min, 37 °C) and intestinal conditions (pH 7.5, 5 h, 37 °C). Significantly improved cell viability showed that microencapsulation of B. lactis 10140 with the prebiotics was successful in producing a stable symbiotic powdery nutraceutical.

    The flood that hit Kelantan in December 2014 was the worst in Malaysian history. Women and their infants accounted for a large proportion of the people at risk who were badly affected, as almost half of the population in Kelantan was in the reproductive age group. This report serves to raise awareness that breastfeeding mothers and infants are a special population with unique needs during a disaster. Four of their concerns were identified during this massive flood: first, the negative impact of flood on infant nutritional status and their health; second, open space and lack of privacy for the mothers to breastfeed their babies comfortably at temporary shelters for flood victims; third, uncontrolled donations of infant formula, teats, and feeding bottles that are often received from many sources to promote formula feeding; and lastly, misconceptions related to breastfeeding production and quality that may be affected by the disaster. The susceptibility of women and their infant in a natural disaster enhances the benefits of promoting the breastfeeding rights of women. Women have the right to be supported which enables them to breastfeed. These can be achieved through monitoring the distribution of formula feeding, providing water, electricity and medical care for breastfeeding mothers and their infants. A multifaceted rescue mission team involving various agencies comprising of local government, including the health and nutrition departments, private or non-governmental organizations and individual volunteers have the potential to improve a satisfactory condition of women and infants affected by floods and other potential natural disasters.

    Introduction: In Klang, a district in the state of Selangor in Peninsular Malaysia, the effects of westernization and urbanization in recent years have had an impact on infant feeding. The objective of this study was to evaluate the practice, knowledge and attitude to breastfeeding and to assess factors associated with breastfeeding among women in Klang, Malaysia. Materials and Methods: A cross-sectional study was carried out between June and October 2006 involving 220 women with infants aged six months from two randomly selected health clinics were selected and interviewed. Data on socio-demographic, infant factors, infant feeding in the first six months of life, knowledge and attitude towards breastfeeding were collected. Results: Exclusive breastfeeding was reported by 32.8%, mixed feeding was reported by 14.5% and infant formula feeding was reported by 52.7% of the respondents. Chinese women were more likely not to practice exclusive breastfeeding compared to Malay women (odds ratio 18.27, 95% CI: 3.95, 84.54) while working women were more likely not to practice exclusive breastfeeding compared to non working women (odds ratio 3.75, 95% CI: 1.64 , 8.55). Positive association with not exclusive breastfeeding included women with high household income and women with male infants. Malaysian women had a positive attitude but work place and short maternity leave had a negative impact on breastfeeding. Conclusion: Women of Chinese ethnicity, working, from high family income and with male infants were less likely to exclusively breastfeed. Adopting facilitatory measures at hospitals and work place could increase the rate of exclusive breastfeeding.

    BACKGROUND: There is presently no certainty about the ideal feeding intervals for preterm infants. Shorter feeding intervals of, for example, two hours, have the theoretical advantage of allowing smaller volumes of milk. This may have the potential to reduce the incidence and severity of gastro-oesophageal reflux. Longer feeding intervals have the theoretical advantage of allowing more gastric emptying between two feeds. This potentially provides periods of rest (and thus less hyperaemia) for an immature digestive tract.

    OBJECTIVES: To determine the safety of shorter feeding intervals (two hours or shorter) versus longer feeding intervals (three hours or more) and to compare the effects in terms of days taken to regain birth weight and to achieve full feeding.

    SEARCH METHODS: We used the standard search strategy of Cochrane Neonatal to run comprehensive searches in CENTRAL (2020, Issue 6) and Ovid MEDLINE and Epub Ahead of Print, In-Process & Other Non-Indexed Citations, Daily and Versions, and CINAHL on 25 June 2020. We searched clinical trials databases and the reference lists of retrieved articles for randomised controlled trials (RCTs) and quasi-RCTs.

    SELECTION CRITERIA: We included RCTs and quasi-RCTs comparing short (e.g. one or two hours) versus long (e.g. three or four hours) feeding intervals in preterm infants of any birth weight, all or most of whom were less than 32 weeks' gestation. Infants could be of any postnatal age at trial entry, but eligible infants should not have received feeds before study entry, with the exception of minimal enteral feeding. We included studies of nasogastric or orogastric bolus feeding, breast milk or formula, in which the feeding interval is the intervention.

    DATA COLLECTION AND ANALYSIS: We used standard methodological procedures expected by Cochrane. We used the GRADE approach to assess the certainty of evidence. Our primary outcomes were days taken to achieve full enteral feeding and days to regain birth weight. Our other outcomes were duration of hospital stay, episodes of necrotising enterocolitis (NEC) and growth during hospital stay (weight, length and head circumference).

    MAIN RESULTS: We included four RCTs, involving 417 infants in the review. One study involving 350 infants is awaiting classification. All studies compared two-hourly versus three-hourly feeding interval. The risk of bias of the included studies was generally low, but all studies had high risk of performance bias due to lack of blinding of the intervention. Three studies were included in meta-analysis for the number of days taken to achieve full enteral feeding (351 participants). The mean days to achieve full feeds was between eight and 11 days. There was little or no difference in days taken to achieve full enteral feeding between two-hourly and three-hourly feeding, but this finding was of low certainty (mean difference (MD) ‒0.62, 95% confidence interval (CI) ‒1.60 to 0.36). There was low-certainty evidence that the days taken to regain birth weight may be slightly longer in infants receiving two-hourly feeding than in those receiving three-hourly feeding (MD 1.15, 95% CI 0.11 to 2.20; 3 studies, 350 participants). We are uncertain whether shorter feeding intervals have any effect on any of our secondary outcomes including the duration of hospital stay (MD ‒3.36, 95% CI ‒9.18 to 2.46; 2 studies, 207 participants; very low-certainty evidence) and the risk of NEC (typical risk ratio 1.07, 95% CI 0.54 to 2.11; 4 studies, 417 participants; low-certainty evidence). No study reported growth during hospital stay.

    AUTHORS' CONCLUSIONS: The low-certainty evidence we found in this review suggests that there may be no clinically important differences between two- and three-hourly feeding intervals. There is insufficient information about potential feeding complications and in particular NEC. No studies have looked at the effect of other feeding intervals and there is no long-term data on neurodevelopment or growth.

    We aimed to investigate the relationship between genetic and environmental exposure and vitamin D status at age one, stratified by ethnicity. This study included 563 12-month-old infants in the HealthNuts population-based study. DNA from participants' blood samples was genotyped using Sequenom MassARRAY MALDI-TOF system on 28 single nucleotide polymorphisms (SNPs) in six genes. Using logistic regression, we examined associations between environmental exposure and SNPs in vitamin D pathway and filaggrin genes and vitamin D insufficiency (VDI). VDI, defined as serum 25-hydroxyvitamin D3(25(OH)D3) level ≤50nmol/L, was measured using liquid chromatography-tandem mass spectrometry (LC-MS/MS). Infants were stratified by ethnicity determined by parent's country of birth. Infants formula fed at 12 months were associated with reduced odds of VDI compared to infants with no current formula use at 12 months. This association differed by ethnicity (Pinteraction=0.01). The odds ratio (OR) of VDI was 0.29 for Caucasian infants (95% CI, 0.18-0.47) and 0.04 for Asian infants (95% CI, 0.006-0.23). Maternal vitamin D supplementation during pregnancy and/or breastfeeding were associated with increased odds of infants being VDI (OR, 2.39; 95% CI, 1.11-5.18 and OR, 2.5; 95% CI, 1.20-5.24 respectively). Presence of a minor allele for any GC SNP (rs17467825, rs1155563, rs2282679, rs3755967, rs4588, rs7041) was associated with increased odds of VDI. Caucasian infants homozygous (AA) for rs4588 had an OR of 2.49 of being associated with VDI (95% CI, 1.19-5.18). In a country without routine infant vitamin D supplementation or food chain fortification, formula use is strongly associated with a reduced risk of VDI regardless of ethnicity. There was borderline significance for an association between filaggrin mutations and VDI. However, polymorphisms in vitamin D pathway related genes were associated with increased likelihood of being VDI in infancy.
